Physical Properties Setup

  • Physical properties are stored in directory constant
  • Let us look in it:
    # ls $FOAM_RUN/icoFoam/cavity/constant
    polyMesh  transportProperties

  • In the directory one can also find computational mesh and one configuration file transportProperties
  • There may be numerous files, depending on the solver
  • Let us write the file transportProperties as a standard output:
    # cat $FOAM_RUN/icoFoam/cavity/constant/transportProperties
